Objective To report a case of juxtaglomerular cell tumour of the kidney (reninoma) in a child treated with laparoscopic nephron-sparing surgery. Patients and results A 14-year-old girl was incidentally found to have hypertension (180/114 mmHg) at the time of adenotonsillectomy. Pre-operative investigations revealed a plasma renin level of 225.9 ng/dl (4.4–46), normal aldosterone, cortisol and urinary catecholamine. Abdominal ultrasound detected a 1.9 × 1.5-cm hypoechoic lesion in the right kidney lower pole; CT scan confirmed the presence of a 1.5-cm, circumscribed, solid, hypoenhancing cortical lesion in the right lower pole. Laparoscopic nephron-sparing surgery was accomplished by clamping the renal artery for 30 min; after excision, the tumour bed was closed using barbed V-loc sutures. The procedure was completed laparoscopically in 150 min with no peri-operative complications. The patient was discharged home on day 4 postoperatively. Histology confirmed the diagnosis of a juxtaglomerular cell tumour that was completely excised. The J-J stent was removed 1 month later. At follow-up, the patient's blood pressure was normalized and medications were stopped. A DMSA scan confirmed 36% residual right kidney function. Conclusion Laparoscopic nephron-sparing surgery should be considered in children with juxtaglomerular tumours. This technique allows prompt recovery with preservation of significant renal function.
